LOCK.

Application filed April 26, 1917. Serial No. 164,723.

To all whom it may concern:

Be it known that I, OSCAR C. KROSHAUG, a citizen of the United States, residing at Volga, in the county of Brookings and State of South Dakota, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to hardware, and more particularly to locks for barn, shed, garage and similar doors.

The object of the invention is to provide a quick acting, strong, simple and cheap lock of this character which is especially designed for use on large high doors for securing them both at the top and bottom and which is operable from a point within convenient reach.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a transverse section of a building equipped with this invention looking toward the inside of the doors,

Fig. 2 is a vertical section taken on the line 2-2 of Fig. l,

Fig. 3 is an enlarged detail view of the interior of the doors showing the lock in open position. i In the embodiment illustrated, a building B is shown having a pair of double doors D D, such as are usually employed on barns, stables and the like.

The lock constituting this invention eomprises a pair of locking bolts or rods 1 and 2 which are pivotally connected at their inner ends with the ends of a lever 3 which is fulcrumcd intermediately of its ends on a substantially inverted U-shaped support t mounted on one of the doors D and which is here shown disposed on the inner face thereof with the terminals oflthe legs thereof extended laterally outward and apertured to Form attaching means. This lever 3 has a handle 5 as shown clearly in Fig. 2 to afiord a convenient gripping member for actuating the lever to throw the rods into and out of locking position, it being obvious that when these rods are in longitudinal alinement they Specification of Letters Patent.

' When it is set inward be u'llu race of the door frame as shown Patented Feb. 19, 3.91%.

will be projected into locking position and when they are disposed out of alinement and in parallel planes as shown in Fig. 3, they will be in released or retracted position and which release is accomplished by swinging the lever 3 into the position shown in dot-ted lines'in Fig. 3.

Guides 6 and 7 in the form of keepers are shown arranged at the upper and lower ends of the door respectively and through which the locking ends of the rods are designed to pass and be guided preventing their accidental disengagement from the door. A keeper 8 is shown arranged on the upper cross bar 9 of the door frame in alineinent with the keeper 6 when the door is in closed position as is shown clearly in Fig. 1, and into which the end of rod 1 is designed to project for locking the door at its upper end. The door sill S is shown providedwith socket 10 in its upper face adjacent the outer face of the lower end of the door D which carries the lock and which is designed to receive the lower end of rod 2 when the lock 80 is in operative position as is shown clearly in Fig. 2.

It is to be understood that whi keeper is shown on the outer face cross bar 9 at the top of this door, a; socket 10 in the sill thereof, that ii struction may be varied according to tho flush with the bar 9 as shown at the l*1g. 2 that the keeper will be einpl e receive the end of rod 1 i tom of Fig. 2 the socket may he to receive the rod.

It is also to he understood tl member 4; shown for suppo. tn 3, the object being to space the ficient distance from the face of the permit its free turning, and the of the rods without engagement door.

The handle member structed of resilient r turned end 5 theree' ward beyond rod 2 is swung into opera the handle arrang i. 2 will bear against red against accidental tu holdin," the doors In the operation oi this lock, the doors .t'rom engagement with the keeper 8 and socket 10 respectively. and thus unlocking the door. To lock the door, the operation is reversed, the handle being moved dow-n-' \vardly. therein" swinging the lever upwardly and bringingirods l and 2 into-longitudinal ali'nement causing their free ends to project into locking engagement with keeper N and socket 10.

While this lock is shown and is preter- .ably used on the inside of a door, it is obvious thatit maybe used on the outside there of and the handle 5 is shown provided with anotch 5in its-terminal which engages rod 2 when sprung into operative position thereby securely holding the lever against; accidental movement such as would be likely to disengage the locking rods. I

The structure shown is -ver.y simple, quick acting and strong, rendering it particularly adapted for the purpose for which it; is designed and by making rod.2 shorter than rod 1, the actuating lever may be positioned at a point. convenient for use b; an ordinary person withont any uiniecessary reaching up.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of'the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the device which I now consider to be the best emlmdimei'it; thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

The combination with a doorframe having rod receiving sockets; of a door having rod guides arranged at its, upper and lower ends on one face thereof and in longitudinal alinement with each other and with said sockets when the door is closed, a pair of lot-king rodsmounted to slide in said guides, at substantially inverted U-shaped support having a minals ot its legs bent laterally out and apertured vtor attachment to the door, a lever in the form of a metal bar fulcrunied intermediately of its ends on the cross bar of said support and pivotally connected at opposite sides of its fulcrum on tihe'inner ends of said rods, said lever having a substantially inverted U-shaped longitudinal evtension at one end otfset laterally from the body of the lever and-rigidly secured at.- the end of one leg thereto, to form a handle therefor, said handle having its free leg turned inwardly and extended into a plane beyond that of the lever body and having a notch in its terminal for locking engagement with the rod on which itis superposed when the parts are in operative position and whereby the rods are held against accldent'al release from the socket.

In testimony whereof I atlix my signature n1 presence of two witnesses.
